The problem of this study is the identification of differences in reading interests and preferences of Indian, Black, and white adolescents of both sexes and from different high school grade levels as they are related to (a) educational background of the parents, (b) availability of reading materials, (c) community size, and (d) the extent to which these preferences are represented in the standard selection aids for secondary school reading materials. A reading interest inventory was administered in the fall term, 1972, through English classes in twenty integrated schools in Oklahoma, representing three levels of population concentration. Community resources in reading materials available through school libraries, public libraries, and bookstores were evaluated. The reading inventories of 3,581 students were chosen to be evaluated to determine if there were significant differences at the .05 level. Earlier studies have indicated that sex and age are major factors in determining what teenagers read about and that adolescents' reading interests tended to be unique, personal, and very unpredictable.- Few studies have been reported that involved ethnic origin or family levels of education.
